thread state of the thread calling mainloop() (or another event
handling function) rather than the thread state of the function that
created the client data structure.
2-digit years are now converted using rules that are (according to
Fredrik Lundh) recommended by POSIX or X/Open: 0-68 mean 2000-2068,
69-99 mean 1969-1999.
2-digit years are now only accepted if time.accept2dyear is set to a
nonzero integer; if it is zero or not an integer or absent, only year
values >= 1900 are accepted. Year values 100-1899 and negative year
values are never accepted.
The initial value of time.accept2dyear depends on the environment
variable PYTHONY2K: if PYTHONY2K is set and non-empty,
time.accept2dyear is initialized to 0; if PYTHONY2K is empty or not
set, time.accept2dyear is initialized to 0.
I had to make a slight diddle to work with Python 1.4, which
we and some of our customers are still using. :(
I've also made a few minor enhancements:
- You can now both get and set the memo using a 'memo'
attribute. This is handy for certain advanced applications
that we have.
- Added a 'binary' attribute to get and set the binary
mode for a pickler.
- Added a somewhat experimental 'fast' attribute. When this
is set, objects are not placed in the memo during pickling.
This should lead to faster pickling and smaller pickles in
cases where:
o you *know* there are no circular references, and
o either you've:
- preloaded the memo with class information
by pickling classes in non-fast mode or by
manipilating the memo directly, or
- aren't pickling instances.
1. Only DECREF the class's module when the module is retrieved via
PyImport_Import. If it is retrieved from the modules dictionary with
PyDict_GetItem, it is using a borrowed reference.
2. If the module doesn't define the desired class, raise the same
SystemError that pickle.py does instead of returning an AttributeError
(which is cryptic at best).
Also, fix the PyArg_ParseTuple in cpm_loads (the externally visible
loads) function: Use "S" instead of "O" because cStringIO will croak
with a "bad arguments to internal function" if passed anything other
than a string.
gethostbyaddr(). (Plain gethostbyname() returns only the IP address.)
This moves the code shared by gethostbyaddr() and gethostbyname_ex()
to a subroutine.

exceptions:
posix_error_with_filename(): New function which calls
PyErr_SetFromErrnoWithFilename()
The following methods have been changed to call
posix_error_with_filename():
posix_1str()
posix_strint()
posix_strintint()
posix_do_stat()
posix_mkdir()
posix_utime()
posix_readlink()
posix_open()
INITFUNC(): os.error (nee PosixError) is PyExc_OSError
